Solution Overview

Problem

Existing devices for arranging double-sided adhesive foil on cylindrical holders in flexo-printing are space-inefficient and poorly accessible, requiring manual operation that is time-consuming and lacks precision.

Innovation Solution

The device positions the foil roll at an angle between 0° and 90° relative to the cylindrical holder, utilizing a manipulator for automated foil handling and cutting, and incorporates a pressing roller for seamless foil placement, allowing for increased accessibility and reduced personnel requirements.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If the foil roll is placed in front of the cylindrical holder for manual unwinding, then the foil can be arranged on the holder, but the device takes up excessive space and the holder becomes poorly accessible

Engineering Contradiction:
Improvespace usageVSAvoidaccessibility
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The patent repositions the foil roll from a front-facing location to a lateral position adjacent to the cylindrical holder. The axis of the foil roll is oriented at an angle between 0° and 90° relative to the axis of the cylindrical holder, creating a spatial arrangement that reduces the device's footprint while maintaining operational accessibility. This dimensional reconfiguration allows the holder to be accessed from the front without the foil roll obstructing the workspace.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Productivity

If manual operation is used for unwinding and placing the foil, then the process can be performed, but it is time-consuming and lacks precision

Engineering Contradiction:
Improvespeed and accuracyVSAvoidtime consumption
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The device incorporates automated mechanisms that enable the foil roll to feed foil onto the cylindrical holder without requiring continuous manual intervention. The geometric arrangement and mechanical components work together to automatically guide and position the foil, reducing both time consumption and improving placement precision.

Inventive Principle:
Principle #25Self-service

3Device complexity

If the foil roll axis is parallel to the cylindrical holder axis, then the setup is simple, but the device occupies more space and reduces accessibility

Engineering Contradiction:
Improveconfiguration simplicityVSAvoidspace occupancy
Core Design Contradiction:
Device complexityVSArea of stationary object

Solution Approach 1:

The patent introduces an angular relationship between the foil roll axis and the cylindrical holder axis, where the angle ranges from 0° to 90°. This angular configuration optimizes space utilization by arranging components in a more compact lateral arrangement rather than extending the device lengthwise, while maintaining configuration simplicity through straightforward geometric relationships.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

The invention relates to a device and a method for arranging double-sided adhesive foil (10) on a cylindrical holder (5) for a flexible printing plate, wherein the device comprises a frame (2), at least one shaft bearing (3) placed in the frame for bearing-mounting of a shaft (4) connected to the cylindrical holder (5), and foil roll bearings for a roll of foil (9), and a support plate (14) with a support surface for the foil, and the projection of the axis between the foil roll bearings onto the support surface extends at an angle differing from 0° relative to the projection of the axis between the shaft bearings onto the support surface. The projection of the foil axis onto the support surface preferably extends transversely of the projection of the axis. The foil is hereby moved in the direction of the axis of the shaft bearings and the foil is fixed in this direction on the cylindrical holder.
